This attitude is taken on the grounds that the man who works with vacuum-tube voltmeters is at least familiar with the vacuum tube. The beginner who is first learning elementary facts about radio theory, has no need for data on vacuum-tube voltmeters. At the same time, the use of equations relating to vacuum-tube voltmeter opention, such as are usually expected by the engineer, are also omitted because of the practical laboratory work that was done during the preparation of this text. The engineer who is interested in one certain type of vacuum-tube voltmeter, will find that type not only described, but presented in completed form with full constants for all of the components. Furthermore, since this is a practical book, rather than a theoretical book, there is no particular need for formulae. :: CONTENTS :: Fundamentals of Vacuum-Tube Voltmeters Diode Vacuum-Tube Voltmeters Triode Vacuum-Tube Voltmeters Rectifier-Amplifier Vacuum-Tube Voltmeters Tuned Vacuum-Tube Voltmeters Amplifier-Rectifier Vacuum-Tube Voltmeters Slide-Back Vacuum-Tube Voltmeters Vacuum-Tube Voltmeters for D-C Voltage, Current, and Resistance Measurements Probes For RF and DC Design and Construction of Vacuum-Tube Voltmeters Calibration and Testing of Vacuum-Tube Voltmeters Applications of Vacuum-Tube Voltmeters Commercial Vacuum-Tube Voltmeters Maintenance and repair of Vacuum-Tube Voltmeters SECTION 1 FUNDAMENTALS OF VACUUM-TUBE VOLTMETER Advantages of the V-T Voltmeter ~~ A Simple D-C V-T Voltmeter Simple A-C V-T Voltmeter ~~ Importance of Waveform—Peak, RMS, and Average Values V-T Volt meters Respond to Peak, Average, or RMS Values ~~ Balancing or “Bucking” Circuits SECTION 2 DIODE VACUUM-TUBE VOLT METERS The Diode Characteristic ~~ Diode Rectifier Operation ~~ Simple Diode V-T Voltmeter Peak Diode V-T Voltmeter—Series Type ~~ Peak Diode Voltmeter—Shunt Type Shunt-Type Diode Voltmeter Circuit ~~ High-Voltage Shunt-Type Peak V-T Volt­Meter Values of R and C for Peak V-T Volt meters “Con­tact Potential” Effect in Diode V-T Volt meters Slide-Back Diode V-T Voltmeter for Positive Peak Voltages Slide-Back Diode V-T Voltmeter for Negative Peak Voltages Slide-Back Diode V-T Voltmeter for Trough Voltages SECTION 3 TRIODE VACUUM-TUBE VOLT METERS Plate Detection V-T Volt meters ~~ Half-Wave Square-Law V-T Volt­meter Half-Wave V-T Voltmeter Using 1N5-GT ~~ Full- Wave Square-Law V-T Voltmeter Full-Wave V-T Voltmeter Using 1N5-GT ~~39.
